Abstract
Background
Internal hernia (IH) is an infrequent complication following colorectal resection with minimally invasive technique. The real prevalence is difficult to define and there are only few large series reporting data on this complication, often focusing only on left-sided resections. Aim of the study was to evaluate the occurrence of IH following laparoscopic colorectal resection (LCR), reporting clinical presentation and treatment.
Methods
Data from 1297 patients undergoing elective LCR for cancer or benign disease in a 15-year period (June 2005–March 2020) were prospectively collected. A database query was performed to search for small bowel obstructions requiring reintervention.
Results
Five patients presented symptomatic IH (prevalence = 0.38%) and required reintervention. The preceding surgical procedure was left hemicolectomy for diverticular disease in all patients. The mesenteric defect had been originally closed in 4/5 patients. The median time interval between initial surgery and the occurrence of IH was 1 (range: 0.3–10) month. In all cases a small bowel loop was found herniating through the mesocolic defect. Small bowel resection was required in one patient only. The median hospital stay following reintervention was 7 (range: 4–17) days.
Conclusions
IH following LCR is a rare but severe complication, potentially leading to death, if not promptly diagnosed and treated. Awareness of this complication, early recognition, and proper diagnostic and therapeutic management is mandatory allowing laparoscopic approach and often avoiding small bowel resection.
